7.3.1. Connecting Power to BSDUs
The BSPS’s DC Distribution unit provides circuit breakers for distributing power
output to BSDUs housed in the WipLL cabinet.
The DC Distribution unit contains a switch that provides an LVD circuit bypass
option. When this switch is activated the battery is no longer protected against deep
discharge and the system controller alarm is then activated.
The distribution rack is provided with front panel and rear panel terminations for
connecting to the BSPS main power rack.
To connect the BSPS DC power supply to the BSDU:
1. Attach the shielded power cable connector (supplied) end that contains the wire
for preventing power radiation, to the BSDU’s power port—labeled

48 VDC. Ensure that the black-colored (i.e., negative) half of the connector is
positioned at the top and the red-colored (i.e., positive) half at the bottom.
